Like numbers of reference refer to the same or similar parts throughoutthe several views.

Referring in detail to the drawings there is shown a portion of adriving wheel I5 of a locomotive as well as its rim I6 and ange I 1.There is also indicated a portion I8 of the locomotive frame to whichthe device is attached.

On the frame portion I8 is secured by means of a bolt I9 a horizontalbase 26 having a circular boss 2l on its upper side, upon which is tteda cylindrical reservoir 22 for lubricant 23.

Depending from the base is a housing 24, to the lower end of which ishinged a shoe by means of the bolts 26.

Mounted in the base 20 are the parallel chain tubes 21 and 28, the lowerends of which are held by the bolts 26. The shoe 25 contains thebushings 29 which journal on the bolts 26.

Transversely across the housing 24 is a shaft 30 on which is keyed adriving sprocket wheel 3I which extends through slots 32 in the tubes 21'15.;Ciaime., (ci. isi-s) and 28. Acrosstheiupper' end'smff thevl tubes21-k and 28 is a yoke 33 which supports a pair of' shafts 34.r` onwhicharegmounted the groovedfy rolls 35.y

Near the inner end of and integral with the shaft 66 is aneccentric 62 on one end of which are the clutch teeth 63 which normallymesh with clutch teeth 64 on the gear 56 under the urging of the spring65. The shaft 60 is further supported by the anti-friction bearing 66. Asecond eccentric 61 is placed on the eccentric 62 and journals in theplate 68. The eccentric 61 lais a radial slot-69 into which projects theDin The plate 68 has rigidly secured thereto, by means of the rivets 10,a finger 1I having teeth 12 which engage the teeth in the ratchet wheelratchet wheel 54. The purpose of this structure is merely to convert avariable eccentric motion into a rotary driving motion; that is, as theposition of the eccentric 61 is determined by the turning of the handle6l, so is the stroke of the eccentric determined and, therefore, theamount; of rotary motion imparted to the wheel 54. An intermediatepinion 'Il on the shaft 18 meshes with the gear 560. An intermediategear 19 on the shaft 18 meshes with the pinion 80 on the main driveshaft 8l which journals in the swing housing 5| and carries on its end arubber tired wheel 82 which engages the track engaging portion of thewheel rim I6 and frictionally drives the mechanism.

It can be seen from the foregoing that, as the device is operated,lubricant is carried by the` chain 41 to the flange Il where thelubricant is deposited.

The delivery of lubricant can be controlled in a very satisfactorymanner by means of the handle El.

A ller spout 83 and hinged cover 84 are provided for the reservoir 22.An inturned lug 85 is formed on the foot 25 to hold the chain 41 on ythestud 45.

I claim:

1. A lange lubricator comprising a reservoir, a pair of parallel tubesprojecting through and above and below the bottom of said reservoir, adriving sprocket wheel mounted under saidreservoir extending into saidtubes, a loading sprocket wheel in said reservoir between said tubes,rollers above said tubes between said loading sprocket and adjacenttube, a shoe depending from said reservoir having a stud at its lowerend, an endless block chain passing around said stud, through said tubesin mesh with said driving sprocket, thence over said rollers and aroundsaid loading sprocket wheel, means for driving said chain andrmeans forvarying the speed of said chain with relation to the rim speed of thewheel on which it is used.

2. In a ange lubricator thecombination of a reservoir for lubricant, anendless chain extending into'said reservoir, one end of said chaindragging against a wheel flange, a sprocket wheel for driving saidichain, a shaft driving said sprocket wheel, a ratchet wheel keyed onsaid shaft, a swing housing hinged on said ratchet shaft, an adjustableeccentric mounted in said housing, means for varying the stroke of saideccentric, pawls actuated by said eccentric engaging said ratchet wheel,a rubber tired wheel on the swinging end of said housing and gearingbetween the rubber tired wheel and said eccentric whereby the rotationof said rubber covered wheel will drive said eccentric'amd drivesaidchain.

3. A lubricator for locomotive wheel flanges comprising a reservoiradapted to be secured to a locomotive frame, a swing housing hinged tosaid reservoir, an endless chain having a portion thereof extending intosaid reservoir and another portion engaging the locomotive wheel Ilange,a rubber tired wheel mounted at the swinging end of said housing, and agear drive in said housing between said wheel and chain.

4. The lubricator as described in claim 3, together with a bailrevolvablyfmounted in said reservoirrfor maintaining the lubricant in amixed condition and for preventing tunneling through the lubricant bysaid chain.

5. In a lubricator ofthe class described, the combination of abasefmountable on a locomotive frame, a reservoir mounted on said base,a pendant shoe hinged to said base, said shoe having a laterallylprojecting stud atits lower end, normal to the hinge axis of said shoe,a pair of vertical tubes extending through the bottom of saidreservoinanv endless chain passing around said stud andY upwardlythrough said tubes and then bending downwardly into the lubricant insaid reservoir, a drive sprocket wheel extending into said tubes andengaging said chain, and a variable speed drive for said sprocket wheelfrictionally driven from the locomotive wheel.
